Well… Put yourself in customer shoes. Thay want unqie but customzible template. Try to add extra homepage layouts, portfolio styles and more sensable page layouts like services, about us, team etc. That not a big deal and easy to implement, but customers needs to see what they can do with your template.

P.S. No the worst first submission I saw so far. Mine was worse . If got rejection anyway don’t give up. Just take 2-3 marketplace free days and go over again with more experience and fresh look.

I suggest you to drop WebGL animation from template. It’s cool effect, but not applicable for commercial template. I’d like to use this thing on my prev projects, but it’s very memory hungry (just try speed tests). Also color scheme does not work and lack of features.
